...why should Fates give out hunting seals? They're already giving you a currency, two even - gil and GC-seals...

for a quest: you can get hunting allocations on a daily basis for both ARR and HW hunts; they require you to slay specific mobs in the open world.
Some currency is related to some special content and I dont really see why that should change (specially in this case) - we might aswell just get rid of all curreny except one then!
